ACETYLEIIE MINER/S LAMP.

Application filed June 26, 1923.

To all whom it may canoe m:

Be it known that I, AnoLrH C. Brenna, a citizen of the United States, residing at Oakville, in the county of Litcliiield and State of Connecticut, have invented a new and useful Improvement in Acetylene Miners Lamps; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in-

Fig. 1 a View in front elevation of an acetylene miners lamp embodying my invention.

Fig. 2 a view thereof in side elevation.

Fig. 3 an enlarged broken view in vertical section.

Fig. 4 a detached broken view on the same scale of the reflector, with its swivelled nut.

Fig. 5 a detached view on the scale of Figs. 1 and 2 of the reflector-supporting shell.

My invention relates to an improved acetylene miners lamp, the object being to rnrovide simple, convenient and reliable means for mounting the reflector thereof and securing it in place against displace- 30 ment.

lVith these ends in view, my invention consists in an acetylene miners lamp characterized by having the nut, by which the reflector of the lamp is secured in place, mounted in the reflector in which it swivels.

My invention further consists in an acetylene miners lamp characterized as above and having positioning means for preventing the reflector from turning with respect to the shell, whereby the sparking-wheel is maintained in predetermined position.

My invention further consists in an acetylene miners lamp having certain details of construction and combinations of parts as will be hereinafter described and particularly pointed. out in the claims.

In carrying out my invention, as herein shown, I employ a lamp-body consisting of a cylindrical carbide-receptacle 10, and a water-chamber 11 superimposed thereupon and provided with a domical cap 12 having a filler-cap 13 and swept by the usualvalvelever 14:. The lamp is also provided with the usual externally-threaded burner-stem 15 projecting outwardly from the water erial No. 647,809.

chamber 11 at a right angle to the vertical axis of the lamp, which in its form and details may be of any standard. construction.

For securing the reflector 16 in place, I employ a nut 17 provided at its inner end with. an outwardly-turned retaining-flange 18, the nut being in this manner permanently connected with the reflector, so as to freely swivel therein, for being screwed upon, or 1L1151SCfGWCl from, the threaded burner-stem For supporting the reflector firmly with respect to the lamp-body and against canting in any direction, I employ a struck-up sheet-metal supportingor backing-shell 19, circular or cup-shaped in general form, but having its bottom shaped, as shown in Figs. 2 and 3, to conform to the external contour of the water-chamber 11, whatever the contour of the same may be, the said shell being preferably secured to the waterchamber and formed with an opening 20, through which the stem 15 projects outward from the body. It will be suflicient to secure the shell by a drop of solder to the lamp-body, or it may be secured thereto in some other manner, or left free. But whatever the contour of its bottom, which should conform to the exterior contour of the waterchamber, its flanged outer edge 21 will lie in the same vertical plane, so that, when the nut 17, carried by the reflector, is screwed. over the stem 15, the reflector will be positioned and firmy held in the vertical plane.

In order to prevent the reflector from turning, it is preferably provided upon its rear face with a boss or nib 22, for entrance into a positioning-notch 23 in the flange 21 of the shell 19.

Before the nut 17 is turned home on the stem 15, the nib 22 is aligned with the notch 23, so that, when the nut is turned home, the said nib and notch will co-act to prevent the reflector from turning. Incidentally, the said boss and notch insure a predetermined location for the sparking-wheel 2a, which is mounted in the usual manner in a slotted stud 25 in the reflector.

By permanently mounting the nut 1? in the reflector 16, so as to swivel therein, its loss is prevented and its convenient manipulation secured, while by providing means for predetermining the position of the re. fleet-or and for holding it in such position, it is guarded against being accidentally rotated, as, for instance, by the collision of its edge with any overhead obstruction when the lamp is in the hat of the miner.

I claim:

1. In an acetylene miners lamp, the combination with the lamp-body and threaded burner-stem thereof, of a reflector, and a swivelled nut non-removably mounted therein for engagement with the said stem, the said nut projecting forwardly into the reflector for manual operation from the inside thereof.

2. In an acetylene miners lamp, the com bination with the lamp-body and threaded stem thereof, of a reflector, a reflector-supporting shell interposed between the reflector and the lamp body, and a swivelled nut non-removably mounted in the reflector for engagement with the said stem, whereby the reflector is firmly seated upon the said shell, the said nut projecting forwardly into the reflector for manual operation from the inside thereof.

8. In an acetylene miners lamp, the combination with a lamp-body comprising a carbide-receptacle and a water-chamber, of a threaded burner-stem projecting from the said water-chamber, a reflector, a reflectorsupport interposed between the said reflector and water-chamber, conformed to the exterior shape of the said water-chamber and adapted to engage with and support the rear face of the reflector, a swivelled nut for engagement with the said stem, nonremovably mounted in the reflector and projecting forwardly thereinto for manual operation from the inside thereof, and

ieans for holding the reflector against rotation with respect to the said threaded stem and reflector-support.

4. In an acetylene miners lamp, the combination with the lamp-body comprising a carbidereceptacle, and a water-chamber, of

tor supporting-shell interposed between the lamp-body and the reflector, a swivelled nut mounted in the reflector for engagement with the said stem, and means for holding the reflector against rotation with respect to the said shell. r

6. In an acetylene miners lamp, the combination with the 'body and threaded burnerstem thereof, of a reflector, a reflector-supporting she-ll interposed between the lamp-body and the reflector, and a swivelled nut mounted in the reflector for engagement with the said stem, the said reflector and shell being furnished with a locking-notch and complementary projection coacting to prevent the reflector from turning with respect to the burner-stem.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
